However, the environmental and genetic influence remains unclear. For this reason we studied the variations and hemodynamic parameters of the CW in twins using transcranial color-coded sonography (TCCS). Sixty-four twins, 19 monozygotic (MZ) and 13 dizygotic (DZ) pairs from the Italian Twin Registry (average age 45.0 ± 13.7 years) underwent TCCS and risk factor assessment. We examined CW morphology and recorded peak systolic velocity (PSV), end-diastolic velocity (EDV) and pulsatility index (PI). Raw heritability was determined for hemodynamic parameters, whereas concordance and discordance rates were calculated for CW morphological variants. A normal CW anatomy was observed in the majority of MZ and DZ twins (76.5% and 92.3%, respectively). The most frequent variant was a missing anterior cerebral artery (ACA). There was no significant difference in the prevalence of most CW variants depending on the zigosity. Concordance rates were low regarding the presence of variant CW anatomy both in MZ and DZ groups (0.14 and 0.00, respectively). Women had a significantly higher PI in vertebral arteries (VA) and in the right ACA (p = 0.01, p = 0.02 and p < 0.01, respectively). An inverse correlation was observed between hemodynamic parameters and age. Morphological variants of the CW do not seem to be heritable; they are most likely determined by environmental factors. In contrast, hemodynamic parameters of the CW are moderately heritable and this might have implications in the management and prevention of cerebrovascular diseases.

However, the level of genetic determination of IJV dimensions, compliance and distensibility has not been studied yet. 170 adult Caucasian twins (43 monozygotic [MZ] and 42 dizygotic [DZ] pairs) were involved from the Italian twin registry. Anteroposterior and mediolateral diameters of the IJV were measured bilaterally by ultrasonography. Measurements were made both in the sitting and supine positions, with or without Valsalva maneuver. Univariate quantitative genetic modeling was performed. Genetic factors are responsible for 30-70% of the measured properties of IJV at higher venous pressure even after adjustment for age and gender. The highest level of inheritance was found in the supine position regarding compliance (62%) and venous diameter during Valsalva (69%). Environmental and measurement-related factors instead are more important in the sittin...

However, to the best of our knowledge, no studies explored the psychometric properties of this instrument in healthy individuals across the lifespan. We here provide the Italian normative data and present the personality features according to age and gender in a sample of healthy individuals. A cross-sectional study was carried out in a total of 1430 Italian healthy individuals ranging from 13 to 67 years (59.3% females). We evaluated the factorial model of the TCI-125, explored the internal consistency of the scales and carried out univariate analyses of variance for the investigation of age and gender differences in temperament and character dimensions. Confirmatory factor analysis only partially confirmed the factor structure, with some Reward Dependence, Self-Directedness, and Cooperativeness items showing poor fit....

While several studies have highlighted patients&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; concerns, little is known about opinions and preferences of healthy potential donors. Further investigations in this respect may allow communication procedures tailored to participants&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; needs. Based on the Italian Twin Registry, a cross-sectional survey was conducted among twins who had not yet donated biological samples for research. The objective was to assess the importance these potential donors attributed to specific procedures and pieces of communication related to research biobanking. A self-administered questionnaire was constructed and validated. Items were as follows: potential agreement on use of biological samples for research; knowledge of biobanks; and importance given to privacy protection and to communication of general and individual tests results, study objectives, type and amount of participant involvement, location and duration of sample storage, and benefits and potential risks. Multivariate analysis was performed to estimate the association of these items with sociodemographic factors as well as with perceived health status and chronic or long-term diseases. The questionnaire was mailed to 4894 twins aged 18-65 (response rate 34%). One-third of subjects already knew about biobanks, 52% had some knowledge, and 20% were uninformed. A majority expressed unconditional agreement to sample use for research. Only 6% of respondents considered privacy protection not important in research biobanking. Knowledge of biobanks predicted attention to most of the issues. Higher education was associated with more frequent concern about type and amount of involvement, but less frequent concern about place and time of storage, and presence of benefits. Women were more attentive to research biobanking. This study supports the need of procedures tailored on different donors&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; concerns and highlights the social value of population biobanks. Furthermore, the results call for greater efforts in the promotion of research biobanking.

For this purpose, psychometric tools have been developed, such as the Magical Ideation Scale (MIS). This scale investigates attenuated forms of thought transmission experiences, thought withdrawal and aberrant beliefs, related to positive schizotypy. This study aims at providing an Italian version of the MIS and its normative data in the general population from childhood to adulthood, being the first study evaluating subjects under 17year-old. The Italian MIS version was translated by three independent operators and administered to 1378 non-clinical participants, stratified into four age groups (i.e., 8-13, 14-17, 18-24 and 25-34). The unidimensionality of the scale was supported, and its internal consistency was satisfactory (i.e., ordinal Cronbach&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s αs ranging from 0.86 to 0.90 in different age groups), as well as test-retest reliability (i.e., 1-month ICC of 0.82 in a retested sub-sample). Normative data for the age groups were provided. Specific gender and age-related differences in MIS score were found, i.e. females scored higher than males in the 25-34 age group, which in general, as a group, scored lower than all the other age groups. This study provided evidence of reliability for the Italian version of the MIS in childhood and adolescence, for the first time, as well as in adulthood, showing specific gender and age effects in the early adult cohort.

For pneumonia and wheezy bronchitis, shared environmental component was larger among passive smokers, while genetic component was predominant among non-smokers. In the etiology of pneumonia and wheezy bronchitis, parental smoking could be a major familial factor.

Lifestyle habits are known to have an influence; however, its magnitude is still unclear. The aim of this study was to assess the contribution of additive genetic, shared and unshared environmental factors to changes in middle cerebral artery (MCA) mean flow velocities (MFVs) and pulsatility index. One hundred and forty-three Italian twin pairs from Padua, Perugia and Rome (68 monozygotic, 75 dizygotic, 55 ± 12 years) underwent transcranial Doppler sonography of the MCA bilaterally. Univariate quantitative genetic modeling was performed to decompose the phenotypic variance of averaged MFV and pulsatility index into additive genetic, shared and unique environmental effects adjusted by age and sex. MFV was heritable in 30.6% [95% confidence interval (CI) 0.8-67.3%], and shared and unshared environmental factors explained 47.7 and 21.6% of the variance (95% CI 14.4-71.9% and 12.6-32.0%). Pulsatility index was not genetically determined, but unique and common environmental factors were responsible for 54.2 and 38.1% of the variance (95% CI 36.3-71.8% and 0.0-57.8%). These findings underline the importance of identification of the specific genes and common environmental factors related to MFV. Individuals with positive family history of stroke related to the atherosclerosis of MCA might take advantage from preventive ultrasound screening. More emphasis should be placed on the prevention of the known related common environmental factors on MFV and the individual lifestyle risk factors on pulsatility index.
